How To Use Voltmeter Light Bulb
Touch the remaining probe from the multimeter to the side of the light bulb base along the threads.
How to use voltmeter light bulb. Using a multimeter to test a two fila. Checking a common light bulb using a multimeter on the ohm scale. Turn the multimeter dial to the diode setting. Testing to see if it is good or bad. Checking for 120 vac on a light bulb socket assembly.
If not you could have a bad breaker bad wiring or a bad switch. Locate the two wires on the bottom of the bulb and touch a probe to each wire ensuring that the probes do not touch each other or more than one wire. Using a multimeter with the selector switch in volts ac position. Mags how to videos how to use a multimeter for beginners in this video i will help teach you how use a multimeter to test volts ac dc amps and ohms. Test the bulb with the multimeter.
If you read 120 volts the light fixture is good. This article describes how to test for voltage. Touch one probe from the multimeter to the very bottom centre of the light bulb. The multimeter will emit a low voltage through the probes that will test whether the bulb has been burned out. Look for the multimeter needle to sweep across the meter face to the far right if the bulb continuity is good.
Test the bulb for impedance by pressing the one probe on the side of the bulb and the other probe on the bottom. A voltmeter is one of the most useful devices for home electrical testing when used correctly. Keep turning it until you land on the diode setting. If it is not labelled explicitly the diode setting may be represented by the diode circuit symbol. If the bulb is in working order the multimeter will show values from fifteen to twenty.
A digital multimeter will read zero. Insert standard test leads into your multimeter and set it to impedance testing. Before using a voltmeter for the first time learn how to set the device correctly and test it out on a low voltage circuit such as a household battery. You must fix the problem to a point where you have 120 volts at the input to the fixture. Brake and turn signal light bulb for a auto or trailer.
